If the panel is part of the form, then use the panel name (lets call it MyPanel)
Then, add your label controls to the panel - we will assume the label strings are in an array or list called myLabelStrings:
int x = 10;
int y = 10;
foreach (string s in myLabelStrings)
{
Label l = new Label();
l.Text = s;
l.Location.X = x;
l.Location.Y = y;
l.Visible = true;
y += 50;
MyPanel.Controls.Add(l);
}
